I read online that calcium channel blockers or some other kind of blood pressure med should be prescribed as a first line of defense to preventing a first heart attack. Well, I was on a calcium channel blocker for a month and it didn't budge my blood pressure. Then, I went on a beta blocker and whoosh! It came down 25 points top and bottom. So, how should I view this? Should I continue on with the beta blocker even though I never had a heart attack even though it works or should I persevere and go back on a calcium channel blocker? Thanks!View Thread
